Angelina Jolie's baby plans

Angelina Jolie's brother has hinted the actress is ready to have another baby.

Angelina and her long-term partner Brad Pitt - who have three adopted children, Maddox, six, Pax, three, and two-year-old Zahara as well as 17-month-old daughter Shiloh - are being encouraged to expandtheir brood by Angelina's brother James Haven.

When asked if his sister was planning to have more children, James said: "I would assume so, yes. I've even been like, 'So, when are you going to?' "

Last month, Angelina sparked pregnancy rumours after cancelling a lecture in Rimini, Italy, after allegedly discovering she was expecting.

James, who attended the Los Angeles premiere of Angelina's latest film 'Beowulf' with Angelina and Brad on Monday (05.11.07), also revealed the couple's relationship is successful because they have managed to keep the passion alive.

He said: "They just work off each other well. I just think there is a certain energy to it."

James can't wait to work with the couple in the future as they all get on so well.

He said: "We get along great. We talk about movies, we talk about bikes. Kids obviously are a major topic, so it's great. You know, I'm looking forward one day to maybe working with him."
